Description

I had some difficulties to get the wade screw ready properly. I tried the tap-method but was not successful so I decided to try the teeth version. This "thing" will show a method to get a desired amount of teeth into the bolt and how to divide the surface of this screw into exactly same sized teeth.

Instructions

<b>Disc:</b>

Print the PDF file for 16 divisions (this number works fine for me...)

Glue onto thick piece of cardboard

Cut disc out and make centric hole with Ã˜ 8mm

<b>Wade Screw (M8 screw or piece of threaded rod can be used):</b>

Take your screw and mark the position where theets are desired on the screw

Screw the disc you made on one end and secure with nut

Mount into your drill press

Fix your dremel onto the table of the drill press

this is a bit tricky.. I did it by clamping it to some support jigs. I leave the table of the drill press lose (not screwed in position) hanging on lowest level. like this I can centre the dremel once on my wade-screw and each time I pull the table to the screw it will hit the same position.

Fix a wire on the drill press to point to one of the divisions on your disc (pay attention that it is not loose!)

Start the dremel and pull table to the screw. Move drill chuck up and down a bit to get the teeth all over the desired area

After first cut, push table off the screw and turn (by hand) the drill chuck until it lines up with the next division

Repeat step 6 & 7 until you have cut all teeth.

Please mind: This screw design need well tightened nuts because it tries to unscrew itself out of the extruder. Use two nuts or a locknut to fix it in your extruder.

This right here is very nice documentation! I try to favor the right/proper method over the easy/cheap approach. These teeth definitely got "moar NOM" going than those made by a file. Great stuff for us noobs! Thanks!
